DOOR-HANGER.

Specification of Letters Patent.

Patented May so, 1916.

Application filed January 13, 1916. Serial No. 71,949.

To all whom t 'may concern.'

Be it known that I, HENRY L. FnRRIs, a citizen of the United States, residing at Harvard, in the county of McHenry and State of Illinois, have invented a new and useful Improvement in Door-Hangers, o-f which the following is a specification.

My invention-relates to certain new and useful improvements in door hangers and is fully described and explained in the specification and shown in the accompanying drawings, in which Figure 1 is an elevation of my device; Fig. 2 is an elevation of the same with the cover plate removed; Fig. 3 is a top plan with cover plate removed; Fig. 4 is an elevation of the hanger showing the track in section; Fig. 5 is a section on the line 5 of Fig. a; Fig. 6 is an elevation of the sweeper block; Fig. 7 is an elevation of a modified form of hanger.

In the drawing 8 is the track proper, it having a troughed lower part in which the hanger rollers run, and a vertical web attached to the building.

9 is a cover plate which incloses the track.

10 are the rollers of the hanger, these being journaled in a frame 11 to the center of which is pivoted a depending member 12 having a pin 13 extending between the plates of the frame. This depending member 12 curves out laterally through the slot between track and cover plate and thence back to a point below the track where it is attached to the door as may be desired, for example by the adjustable support shown.

The construction so far set forth is generically old and no novelty is claimed for it, it being substantially that of Patent No. 1,104,353, dated July 21, 1914.

It has been found, in the use of covered tracks of the type wherein the rollers run in grooves, that dirt accumulates very rapidly and interferes greatly with the smooth movement of the door. Suchfdirt is partly the scale which falls from the inside of the track and more largely mud which is conveyed into the inclosed space by wasps who try to build nests therein. .To remove this objection to inclosed trough-shapedtracks and place them on an equality in this respect with closed tracks slotted at the bottom, I supply on the pivot pin 13 a slotted sweeper block 14. This rests lightly on the bottom of the trough in the track 'and pivots around its support so as to present one of the angular toes which are at its lower end to the groove as the hanger moves. This block, in sliding along, simply sweeps any dirt ahead of it, out of the path of the hanger. I prefer to perforate the track at intervals as shown so thatl this dirt can fall out, but if this be not done the dirt will simply be swept along out of the part of the track in which the hangers run, or beyondv their normal limits of movement.

The modified hanger of Fig. 7 is a single roller hanger of kobvious form with the sweeper block mounted at one end to secure the result above outlined. y

I realize that considerable variation is possible in the details of this construction without departing from the spirit of my invention; therefore I do not intend to limit myself to thespecific form herein shown and described except as pointed out in the following claim, in which it is my intention to claim all the novelty inherent in the construction as broadly as is permitted by the state of the art. .A

What I claim as new and desire to secure by Letters Patent is A door-hanger adapted for use with a grooved track and having side plates forming a frame and rollers ournaled therein, a pivot pin extending between the plates of the frame, and a sweeper-block having a slot therein through which the pivot pin extends and provided at its lower end with angular toes, whereby in the movement of the hanger said sweeper-block is adapted to pivot around its support and to present one of its angular toes to the groove in the track to sweep foreign matter therefrom.
